Abstract
The Collaborative Ankle Support Trial (CAST) is a longitudinal trial in which interest lies in the rate of
improvement, the effectiveness of reminders and potentially informative missingness. A model is proposed for
continuous longitudinal data with non-ignorable or informative missingness, taking into account the nature of
attempts made to contact initial non-responders. The model combines a non-linear mixed model for the outcome
model with a logistic regression model for the reminder process. A sensitivity analysis is used to contrast this
model with the traditional selection model, where we adjust for missingness by modelling the missingness process.
